JDBC type 2 and type 4 drivers
The Configuration Wizard uses JDBC type 4 drivers by default. We can change the default selection in the Configuration Wizard.
During step 2, Customize values, click Advanced to change the driver type.
When we use a JDBC type 2 connection, WebSphere Portal and DB2 Connect are installed on one system (the local system). The DB2 server is installed on a different system (the remote system).
When we use a JDBC type 4 connection, we do not need DB2 Connect. Instead, the DB2 Universal JDBC driver supplied with DB2 is copied to portal server. It is used within the Java virtual machine (JVM) of WebSphere Portal and connects directly to the remote DB2 server.
Depending on the database software, there might be more required configuration steps for using type 2 drivers. Review the installing database software topics.
